The answer to 'maintenance not cooling' is that there are several common causes for an HVAC system not cooling properly, including a dirty air filter, low refrigerant levels, a faulty compressor, or issues with the thermostat or electrical components. Symptoms can include the system running constantly, warm air blowing from the vents, or the system not turning on at all.
In many cases, simple maintenance tasks like changing the air filter or cleaning the condenser coils can resolve the issue. However, problems with the refrigerant, compressor, or electrical system will likely require a professional HVAC technician to diagnose and repair. It's important to address cooling issues promptly to prevent further damage and ensure your home stays comfortable.
